Redundancy

Topologies – with or without redundancy

With fewer components and a clear-cut concept (one fibre cable and several switches per office floor), FTTO allows you to design your network in a way that provides all the flexibility you need. Besides a fast, hassle-free installation, you can enjoy easy scalability as your requirements change and your network needs to expand.

Physical Star structure using pre-terminated solutions: fast installation times

In sizeable FTTO installations with a large number of fibre terminations, pre-terminated solutions are often used to meet stringent project time requirements. Aginode Pre-Terms consist of a full dielectric round cable terminated with LC connectors on either end. A high-density fibre optic cable is installed from the central distributor to a junction box. From here, workplaces are connected using two or four fibres. The connection in the zone distribution box is spliced and links to the workplaces use pre-assembled patch cords.

• Pre-terminated fibre assembly (up to 24 fibres) between the building distributor and zone distribution boxes
• High flexibility for future add-ons and changes
• Pre-assembled patch cords to the workplaces (switches)

Physical Ring structure using extractable bundle technology: maximum flexibility of the infrastructure

By using new cabling solutions such as high-density fibre cables with extractable bundle technology, the required effort for the cable installation decreases considerably whilst redundancy is provided. A high-density fibre cable (up to 144 fibres) can be drawn in a loop through selected parts of the building. At any location along the cable, future zone distribution points can be added. This makes it possible to connect new outlets using pre-assembled fibre optic cables.

• Up to 576 active user ports with only one cable
• High flexibility of the infrastructure
• Easy scalability
• Minimum cable volume

WITH REDUNDANCY

FTTO makes it easy to set up ring topologies wherever there is a need for redundancy at the user level. Intelligent managed FTTO switches automatically switch data traffic to a ‘healthy’ fibre path, should a link fail. This guarantees the highest network availability to connected end users. In fact, up to 1,152 active user ports with full redundancy could be serviced with a single cable. Furthermore, the uplink time is shorter.

The following topologies use two building distributors and feature a star connection with small rings of up to four FTTO switches.

• Pre-Terminated - Physical Star Structure
• Redundancy = high availability of the network
• Pre-terminated fibre assembly (up to 24 fibres) between the building distributor and zone distribution boxes
• Short installation time
• High flexibility for future add-ons and changes
• Pre-assembled patch cords to the workplaces (FTTO switches)
